Questions for diagnosing the cause of face swelling

To diagnose the underlying cause of face swelling, your doctor or licensed health care practitioner will ask you several questions related to your symptoms. You can best help your health care practitioner in diagnosing the underlying cause of face swelling by providing complete answers to these questions:

  • What is the exact location of the swelling?

  • Describe the swelling. When did the swelling start? Does it come and go or is it constant?

  • Did you eat any foods or come in contact with any unusual substances preceding the swelling?

  • Are you are experiencing any pain, shortness of breath, or other symptoms?

  • Provide your full medical history, including all medical conditions, surgeries and treatments, family history, and a complete list of the medications and dietary supplements that you take.

Because facial swelling can be due to serious diseases, failure to seek treatment can result in complications and permanent damage. It is important to visit your health care provider when you experience swelling or other unusual symptoms. Once the underlying cause is diagnosed, following the treatment plan outlined by your doctor can lower your risk for potential complications of these conditions including:

  • Difficulty breathing or respiratory arrest from anaphylactic shock

  • Loss of sight from orbital cellulitis

  • Skin or other tissue removal, such as due a serious infection or malignant condition
